Answer:
1.89 M is the molarity of the solution.
Explanation:
Assuming 10.5 kg of the hydrate, we need to calculate the amount of moles in the solution to be able to use the formula Molarity = mol / volume (in Liters).
So, the conversion would look like this:
10.5kg x (1000g/1kg) x (1 mol/299.22g) = 35.1 mol
Then, apply the formula M = mol/L
35.1 mol / 18.60 L = 1.89 M because the answer is 3 sig. figs. because of the "10.5" in the first conversion
